The head of the House science committee falsely claimed the National Science Foundation funds “more than twice as many graduate students in the social and behavioral sciences as in computer science, mathematics or material science.”

Rep. Lamar Smith said climate change “alarmists” ignore the “positive impacts” of more carbon dioxide in the atmosphere, such as increased food production and quality. But the impact of increased CO2 levels on agriculture is more complicated than that — and, on balance, likely negative, particularly in the future.

Rep. Lamar Smith said that, after national security agencies, “NASA received the most favorable budget request from the Trump administration.” True, but President Trump’s 2018 proposal would still cut NASA’s budget by about 3 percent compared with the agency’s enacted budget for 2017.

Top Republicans on the House science committee claim a former National Oceanic and Atmospheric Administration scientist “confirmed” that his NOAA colleagues “manipulated” climate data for a 2015 study. But that scientist denies that he accused NOAA of manipulating data.

Rep. Lamar Smith at a recent hearing claimed a new study published in the journal Nature Climate Change “confirms the halt in global warming.” It doesn’t. In fact, the authors of the paper write, “We do not believe that warming has ceased.”
